Be it known that I, RUSSELL SPAULDING, a citizen of the United States,residingin the borough of Manhattan, city, county,and State usefulImprovements in Electric Conducting- Cables, of which the followingisaspeeification I i My inventionrelates to electric-current- I willdescribe an clectric-current-condncting, cable and then point out thenovel features thereof in the claims. v

In the accompanying drawings, Figure 1 is a detail plan view of aconducting-core employed in the cable einlmdying my-invention. Fig. isan end view'of Fig. 1. Fig. 3 is a detail plan view of a conduetor-cable embodying my invention. Fig. -l is an end view of Fig. 3.Fig. 5 is a detail plan view of a modified form of conductor-cableembodying my' invention. F'g. 6 is an end view of Fig. 5.

Similar letters of reference designate corresponding parts in all of thefigures.

being considerably wider than it is thick; and it consists, essentially,of a core A and an insulating-covering A. The core A consists ofplurality of fine wires, which are braided. "The line wires arepreferably arranged in strands each consisting of a number of wires andthe strands braided. In making the core A it is braided about a mandrelor other iormmjanrl it iseylindrical. ln its cylindrical 55 shape it ispassed through suitable rolls and flattened.ltinaybeflattenedbyotbermeans. 7 The insulating material, which ispreferably of rubber, may be applied atgthe time the core isbcinglath-med by rolls. it may, however, i

be applied in any desired wail. l

(No model)In Figs. 5 and-6 I have shown a modified form 0E e'onduetm'. .Itconsists of a plurality of eorsA, inclosed by a: singleinsulatingcovering'flk'. ,1 have shown two cores; but it is obviousthatany number. maybe inelosedq 5 .by a single insulating-covering.Between each core'a vertical wally.- of insulation is placed. The wallis preferably integral with the other adjacent parts of the covering.

Acable made inthis manner possesses great tensile strength and isextremely flexible.
